Impacts of anthropogenic activities & climate change resulting from increasing concentration of Carbon dioxide on environment in 21st Century; A Critical Review

Abstract

Abstract The human population explosion and rapidly increasing urbanization are two major problems of the current century. According to an estimate world human population is about 8 billion, while in the previous century, it was about 2.0 billion. These figures and facts shows that the future impacts of anthropogenic activities will be more harsh and comprise a more complex nature. Carbon emission induced in environment by anthropogenic activities is major cause for global warming. Climate change, different types of environmental pollution, wastage of raw materials, and ecosystem degradation are major important ecological challenges which are being faced by humanity. These problems are increasing every year due to increasing human population. Forests represent one of most frequent types of green area in cities. Their environmental settlement include perfection in air, water and soil quality, conservation of energy, carbon sequestration, low air temperatures, reduction in ultraviolet radiation and reduction in environmental pollution especially air pollution. The political ecology approach is based on interactions between humans and nature, talking about climate change mitigation and adaptation and technologies that are used for these purposes. Many environmental experts have initiated concept of green revolution to achieve mitigation and adaptation strategies. If human population explosion and establishment of new industrial structures go on increasing without considering the importance of trees then certainly there would be more critical changes for living organisms on surface of the earth in near future. So, “green revolution is the best solution to arrest the environmental pollution” in this changing climate of the world.
