An environment is the natural world that surrounds us. It is very important to keep it clean in order to live healthy and peaceful life. However, the environmental pollution has become one of the biggest threats for Earth. It can affect our future one day. People suffer from their own mistakes. Pollution endangers our existence and destroys our living environment. The future will either be green or not at all.
People are considered to be the most intelligent creatures on Earth who are able to learn new things in the universe which can lead them to the technological advancement. It goes without saying that there are many benefits in technological development for the economy but it also destroys our environment gradually. We develop technologies and science to make our life better but we do not fall to thinking that it can ruin everything that surround us in the near future. The destructive human activity cause several adverse effects on environment. The effects of pollution are devastative. It is very important to explore the various types of pollution and all possible ways of their prevention in order to make our planet a safe place for the growth and development of all living things.
Water pollution is one of the pivotal problems nowadays. A lot of garbage is thrown directly into the water. Moreover, a lot of factories, mills, and plants discharge the untreated industrial wastes and other unsafe substances into the water bodies. Water is also polluted by fertilizations and pesticides which are widely used in agriculture. The contamination of the living environment leads to the deaths of the entire natural ecosystems. There are many approaches to garbage utilization but most of the poor countries just don`t have enough money to introduce such up-to-date technologies. Air pollution is another humanity`s challenge. The air we breathe has contaminated because of uncontrolled release of harmful vehicular and industrial smokes. Burning fuels, nitrogen oxides, sulfur dioxide, carbon monoxide, and chemical vapors are the major pollutants of the air. Sulfur dioxide and carbon dioxide cause a situation called Global warming when the radiation is absorbed while the heat is prevented from escaping. Our environment also suffers from noise pollution which has negative effects on people and wild species.
Environment plays a significant role in making our existence on the planet possible. Everything we use to live a full life comes under the environment. We just can`t live without air, water, land, sunlight, animals, and other natural things. Environmental pollution is affecting our lives physically, emotionally, socially, economically, and intellectually. It has become a major worldwide issue which cannot be solved by the effort of one. We should do our best in order not to put the end to the existence of all living things on earth. Every person on our planet should take a little step to save our environment and maintain its originality.
We should reduce water wastage, save energy, use rechargeable batteries, reuse our old things in new ways, and throw wastes properly to its place only. People use the components of the environment to fulfill their basic needs of living. We should stop polluting and challenging our national resources to ensure sustainable living conditions for our future generations. The usage of non-conventional sources of energy should be encouraged. Restriction on the use of fossil fuels and pollution control laws should be imposed strictly. We have to control the emission of greenhouse gases strictly to save our environment from the threat of Global warming.
The remarkable growth of technological progress has negative impact on the ecological state of our planet. The work of factories and plants and the extraction of natural resources result in serious environmental problems that call for radical actions for environmental rehabilitation and protection. The influence of the devastative human activity shouldn`t be ignored. We should contribute every day to the preservation of our natural environment. Mankind should be sure that technological advances would never disturb the ecological balance of the Earth. Environmental problems should be handled by the united efforts of the global community. Nowadays, a lot of international summits, conferences, and presentations are held to deal with recycling, waste treatment, and water and soil contamination. We should always remember that environmental pollution is an incurable disease. It can only be prevented. So, let`s take care of the world that surrounds us!

Essays on environmental management
species invasion, social capital and energy demand
Essays on environmental management.
This thesis contributes to the economic literature on invasive species, social capital connection to climate change and environmental good provision as well as energy demand management. It contains five independent papers connected by the broader theme of environmental management. Two papers (I and II) deal with invasive species while the third and fourth probes the effect of social capital on carbon dioxide emissions (CO₂) and individuals’ decision to contribute toward environmental protection. The first paper attempts a comprehensive theoretical and empirical review of findings in economics with respect to the challenging question of how to manage invasive species. We find a relatively large body of literature on the assessment of damage costs of invasive species; single species and groups of species at different geographical scales. Estimated damage costs show large variation, from less than 1 million USD to costs corresponding to 12% of gross domestic product (GDP), depending on the methods employed, geographical scale, and scope with respect to inclusion of different species. In the second paper, a simple bioeconomic model is developed and applied to the management of the aquatic invasive species Elodea canadensis (Michx) in Lake Lötsjön in Sweden. A weed harvesting programme is proposed and numerically investigated based on the model. Results suggest that it is economically optimal to engage in the weed cutting programme since it yields positive net economic benefits and that early action is the best strategy. Social capital is the main connecting factor between Paper III and IV. In both papers, different constructs of social capital were computed through principal component analysis and modelled empirically to explain different environmental outcomes. Paper III investigates whether or not social capital explain Swedish county-level aggregate and sectoral per capita CO₂ emissions in an environmental Kuznets curve (EKC) framework. The results showed significant dampening effects of trust and overall social capital indices on total emissions, but impact heterogeneity was evident among sectors. Estimated effects were negative on emissions from industry but positive on transport emissions. In Paper IV, we assess the influence of social capital on individuals’ willingness to contribute toward environmental protection in Sweden. Findings show significant impact of social capital. The fifth paper provides an empirical analysis of energy demand in Ghana. Elasticities of seven key disaggregated energy types were estimated using time series analysis. The results suggest energy prices, income, urbanization and economic structure are significant demand drivers of the different energy types with varying elasticities. Further evidence show high degree of inter-fuel substitution in energy demand in Ghana, particularly from gasoline, diesel and kerosene toward LPG consumption.
