In the present, habitat destruction effects on a large scale, constantly destroying habitats such as oceans and rainforest which leads to biodiversity loss. Learn about the ongoing, tragic consequences of human actions. Fisheries activities are especially ubiquitous across marine habitats, directly affecting virtually every habitat except the deepest sea floors. The melted ice caps and glaciers contaminate the water and this threatens the life of the aquatic plants and animals. In many cases, countries rely on the shipping means of transport for bulky cargo. The increase in temperature has another aeration negative impact. Between 60% and 70% of European wetlands have been completely destroyed. Habitat destruction drives wildlife away, sometimes to extinction. Pollution and effluents from the land travel easily through streams and rivers to the ocean, where they impact the health of fish, birds, and marine plants. Habitat destruction is the process by which natural habitat is damaged or destroyed to such an extent that it no longer is capable of supporting the species and ecological communities that naturally occur there. This activity can be conducted in small groups. Earth Eclipse. One irrefutable assertion is that marine lives are highly appreciated. Every year species is in danger of extinction and The outcomes of it have an impact on the balance and the food chain. Other policies can be formulated which support and give guidance on what needs to be done during coastal urbanization to preserve the marine habitats. Marine life is an important part of the ecology and human have disturbed the ecology by polluting marine life. Habitat destruction can have a significant impact on marine biodiversity as species richness, abundance, distribution, genetic variation and inter-population dynamics are affected and entire ecosystems are altered by the loss of habitat. Perhaps, various environmental conservation bodies such as UNEP can be in liaison with the various governments so that laws seeking to control industrialization and waste disposal are ratified. She loves writing on topics related to space, environment, chemistry, biology, geology and geography.
