I thank the learned audience for providing me with the opportunity to present a short speech on nature.
Nature refers to the natural world. The entire earth consisting of water resources, soils, air, mountains, animals, plants, and human-beings constitutes the nature.
Nature also refers the phenomenons that is not altered by human activities or those that exists even with human intervention.
Natural Ecosystem consists of living and non-living natural elements of the earth that is co-dependent on each other.
Air is the layer of gases that surrounds the earth. The gases that form the air includes nitrogen, oxygen, water vapour, carbon dioxide, carbon monoxide, and other gases.
Ozone layer protects the natural environment by depleting the ultraviolet (UV) rays that reaches the earth.
Oceans are made of salt water. They cover nearly 71 percent of the natural earth’s surface. A large number of marine co-exists within the ocean ecosystem.
Natural fresh water resources include rivers, lakes and ponds. Lakes are larger than ponds and are generally fed with rivers.
Rivers are natural sources of freshwater. Most of the rivers originate from mountains and flow towards the ocean.
Weather changes according to the natural climatic patterns. The variance in weather is caused because the earth’s axis is tilted. This is called seasons. The weather is cold during the winter season and it is very hot during the summer.
Human beings are a small part of the natural world. Humans have been using technologies to make their life easier. They exploit natural resources, and cause deforestation, pollution, global warming, climate change, oil spills, and ozone layer depletion.
The natural marine ecosystem is under threat due to oil spills and pollution. Ozone layer depletion is exposing the earth to the hazardous ultraviolet rays. The earth’s average temperature continually rising, and the climate is not following the natural patterns. For meeting the food requirement, human rely more on agriculture and less on uncultivated plants and forests. A large portion of forests have been cleared for making the room for agriculture.
We can save the nature by:
- using less technology,
- rely more on the natural processes,
- not wasting the natural resources such as water,
- reusing plastic products,
- recycling properly,
- properly disposing wastes,
- planting trees,
- employing organic farming, and
- burning less fossil fuels.
