world’s ecosystems? Every day there are parts of land that are being sold so builders can make buildings. Like new home construction‚ parking lots‚ malls‚ and even restaurants. But do people ever think of what we are taking away by building over certain parts of the land. What if certain species lived there and we took their habitat away. Or what about the swamps and the forest? A lot of things come with those places‚ and we use them for everyday life‚ plants and trees. Doesn’t it bother you that

Acidification on Marine Ecosystems Ocean acidification is the ongoing warming and decreasing of pH in the earths water supply (Gray et al. 2016; PMEL 2017). The acidification is caused from the increase in carbon dioxide concentration within the earths atmosphere. The carbon dioxide then reacts with the water to produce carbonic acid and carbonate ions thus‚ decreasing the pH. Ocean acidification affects the ecology of everything on this planet. Mainly‚ the marine ecosystems and small organisms take

Effects of Human Activities on the Lake Ecosystem I. Introduction On the first exercise of the Environmental Biology class‚ the students have learned what an ecosystem is and what its significance to the survival of the living and non-living are through analysis of forest and agro-ecosystems. The ecosystem as the basic unit for ecological study (Evans‚ 1956) consists of the complex of interacting organisms inhabiting a region with all the non-living physical factors that make up their environment

Guarding our ecosystems- Marshlands and Wetlands In the last decade‚ the conservation of our ecosystem has gained high importance. The last few years have seen a considerable jump on awareness of the conservation of marshlands. Marshlands or wetlands are areas which are transitional between terrestrial and aquatic systems. Here the water is usually at the surface. The land is covered by stagnant water that does not exceed 6 meters. They are considered important as they are home to various species

polluted air‚ and many pollution- associated illnesses have been on the rise. Yet polluters and their allies in Congress have been fighting efforts to reduce toxic industrial pollution and are trying to weaken existing clean air protections. That’s why NRDC has joined other public health‚ advocacy and environmental organizations in the "Clean Air Promise‚" a national campaign to protect the health of children and families across the country from dangerous air pollution.

Finding Nemo a million times‚ or it seems like it anyway! I always loved the scene where Marlin and Dory play the game with the “jellies”. There were so many of them that they couldn’t even see the ocean anymore. Are jellyfish ruining the Earth’s ecosystem with over population? Some people‚ especially fisherman‚ are concerned that this is true‚ but we need to continue to investigate these mysterious creatures to figure out solutions to this potential problem. For most beachgoers jellyfish are just

Natural Ecosystem: Stony Creek Metro Park Natural Ecosystem: Stony Creek Metro Park My pick for this park was based on the fact that this was made in to a natural ecosystem in 1964. A plan was drawn to make this park by making a dam and creating a 500 acre lake in the center of a 4‚461 acre land section from the stony creek (a tributary of the Clinton River). Once the dam was formed the lake was made‚ and the park came together. There are many plants and wildlife in this park‚ and fish in
