Vulnerability and Resilience of Ecosystems * Vunerability is the sensitivity of an ecosystem to cope with stress. * Resilience is the ability of an ecosystem (or a component of an ecosystem) to adapt to a changing environment and to restore function and structure following an episode of natural or human-induced stress. * All ecosystems function in a state of dynamic equilibrium or a continual state of balanced change. * This state of dynamic equilibrium is the product of the interrelationship of the

Environmental Destruction Environmental destruction is the destruction of the environment through depletion of natural resources and pollution. The planets natural ecosystems and regenerating bio-capacity are being severely degraded and as a result this compromises the ability of the planet to sustain life. Forests‚ fisheries‚ oceans‚ rangeland‚ freshwater systems (lakes‚ wetlands‚ rivers) and other natural ecosystems are all threatened whilst many are on the verge of collapse. Water‚ land and

List of Environmental Problems The earth’s environment has become a pervasive and global problem. There is growing awareness about the need to conserve our environment. Read on to know the different environmental problems. Today the earth’s environment is in a sorry state. Wherever one looks‚ one encounters pollution. Forests are disappearing. The green patches in the city are being replaced by concrete buildings. Waste products are being dumped indiscriminately. Water is too toxic to drink.

gathered here today to encourage others to be considerate of the environment. However‚ this poem here in my hand holds all the answers to our problems. Sir Gawain and the Green Knight was written over six hundred years ago‚ but despite this‚ its ecological statements continue to be relevant to our society today. It exposes our fraught relationship with our environment and what we should expect if we continue to disrespect the natural world. Ultimately this poet here has created the first ever eco-poem

There has been a shift in recent years from technologies that are wasteful of resources toward technologies that use resources more efficiently and reduce pollution‚ a shift from conventional economy to sustainable economy. We are living beings on a planet Earth. Humans are living beings who depends on the nature. People use energy and natural resources; everything we have come from natural resources. Our economy depends on what and how

Theories of Biology pg.1 The major theories of biology are evolution of natural selection‚ biological classification‚ inheritance‚ cells‚ bioenergetics‚ homeostasis‚ and ecosystems. Evolution by natural selection is a process that occurs over successive generations. Inheritance is a theory of how characteristics of one generation are derived from earlier generations. Cells theory is that all organisms are composed of cells and that all cells come from preexisting

Conservation is very important to all living things. The environment where organisms live is dependent on conservation. Organisms depend on each other and on their environment. For organisms to continue to exist‚ their environment must also exist. Economic Value. A nation benefits more from an organized‚ clean‚ and unexploited environment because more potential resources can be harnessed from it. As in the birds’ nests in the caves of Palawan‚ natural resources in places that are well taken care of

The Foundation of Society: A Review of Social Contract Theory The Social Contract Theory works as a rule of moral constraints in society for the common good. For Rachels’ perspective‚ “The Social Contract Theory: The right thing to do is to follow the rules that rational‚ self-interested people would agree to follow for their mutual benefit.” (Rachels 158) Based on “self-interested” criteria‚ people “need another enforceable agreement” to last harmonies which are built on this social contract.

then transferred over to machines. These machines required more natural resources such as iron and coal to produce large amounts of steel for tractors‚ pipes‚ and other devices. As the population increased‚ the demand for more products‚ such as clothing‚ shoes‚ and household items required more energy to be produced. The increased use of machines eventually led to an increased need for power. The needed power could only come from natural resources. Causes . Some of the materials needed are renewable
