Write 5 pages with APA style on Effects of Human Action on Environment. Human activities that affect the environment include technology, agricultural, industrial energy, products from manufacturing industries, mining, and transport. These activities have direct and indirect effects on biodiversity, resources, and the biophysical environment. However, over-exploitation of natural resources and pollution has increased at an unprecedented rate and hence affected the environment.
Increased demand for the limited available natural resources because of industrialization and population growth has negatively affected the environment. This is because of the rampant adoption of chemical use like fertilizers, herbicides, and insecticides in order to boost production in the agricultural sector. These products are usually toxic chemicals, and they pollute the air, soil, and water. Biodiversity loss and other changes in the environment have increased currently as compared ever in history (Morris and Chapman 1). There has also been a decline in plant and animal population and an increase in extinction rate of indigenous species. The loss of biodiversity negatively affects the lives of human beings (Morris and Chapman 1). For example, insecurity on food, an increase in the number of natural disasters being experienced, insecurity in the amount of energy produced, and scarce access to clean water and raw materials (Morris and Chapman 1). According to Morris and Chapman, the major causes of biodiversity loss in the environment are grouped into two- direct and indirect drivers. Direct drivers comprise human habitat while indirect drivers include human population growth, economic activities, technology, and social, political, and cultural factors.
According to Hawksworth (339), the three main elements of environment that are affected by human activities are air, soil, and water. Human beings burn fossil fuels for heating, transport and industrial use that pollute the environment. This air pollution has led to global warming, climate change, and an increase in the number of diseases. It has also led to decreased agricultural production because of unpredictable weather changes, which has contributed to food insecurities in the world.
