Environment refers to the interaction between the physical, chemical and biological components.
Ecology is the study of relationship between organisms and their environment
The environmental issues include pollution, deforestation, global warming, and other broader issues.
The ecological issues include population size, diversity, distribution of organisms, and also the competition between them.
Studies the internal and external factors affecting the environment.
Aims to understand life process, distribution, adaptation and biodiversity.
Environment degradation often leads to changes in atmosphere. The water cycle and the natural habitat of plants and animals also changes drastically. The natural biodiversity degrades. Air, water and land pollution adds up to promote these atmospheric changes. The climate and the weather changes owing to increased pollution. This in turn increases global warming that can prove harmful to the generations to come. The rate of depletion of ozone layer multiplies rapidly owing to environment degradation. Human health:
This environment degradation has a negative impact on health of humans. Since there is considerable reduction in the quality of air, water and land, the average life span of humans decreases. Lakhs die due to illness caused by pollution. As the quality of air diminishes, lots of people die due to chronic diseases like lung cancer and heart attack. Landfills on the other hand promote environmental degradation. Hazardous waste from these landfills can easily enter the food chain that can further cause biomagnifications. Apart from all these. Dumping of toxic waste by the industries adds to the pollution which dangerously affects the health of the humans. Biodiversity lost:
Due to continuous degradation of the environment, the natural habitat, the forests, and the ecosystem get disrupted. Most of the species are under the threat of extinction. The reproductive capacity, the ability to withstand the changes in temperature and all are disturbed. All these are mainly due to human activity which has caused exploitation of natural resources, acidifying water resources, soil erosion due to large scale deforestation and making the air impure even to breathe. Al these combined has hampered the natural biodiversity.
