Changing lifestyle, consumerism, degradation of nature and pollution are some of the man-made issues.
All this has resulted in increased concern for the ecosystem. Human population also creates solid waste.
How is urbanization responsible for destruction of ecosystems?
People migrate to cities due to lack of food and other facilities. The city has industries, factories and other facilities, which provide work to many people. Many people migrate towards cities every day. This makes the city grow. The increasing population in cities requires more housing. This leads to loss of agricultural land, marshy land, wetland, forest and grassland areas.Natural ecosystems have been lost to development. Human intervention changes ecosystems. Changing land use destroys many naturally occurring species.
Notes
Ecological system:
Language: In the ecosystem there is mutual action of living (biological) and non-living (abiotic) components.
Bi-composer: Microorganisms have an important role in converting organic matter from dead plants and animal bodies into inorganic substances; This is why they are called “decomposers”.
Structure of ecological system:
Non-Biological Factors: The biotic factors that affect survival and population numbers are influenced by many abiotic factors, including air, water, soil, sunlight, temperature and humidity.
Niche: The position and role of a living organism in an ecosystem is called its “niche”.
Diversity manifested in ecosystems: There are many ecosystems on Earth, classified on the basis of size, location, climate and types of plants and animals.
Biome: “Biomes” are two major types of ecosystems that are similar in climate and abiotic components: biomes, both underground and aquatic.
