With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.
Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.
More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.
Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.
The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.
The answer is C where the star is found in the sky. If a star is moving toward us, its spectroscopy will be observed at shorter wavelengths, this is called "blueshifted". If the star is moving away from us, the lines will appear in longer wavelengths, and that's called "redshifted".
Sorry for a late response, but I hope this helped.

Answer: 1) When phosphorous is not bound in rocks, it moves quickly through land food webs. Constant use of phosphate-rich fertilizers will help increase phosphorus availability to plants, thus ultimately helping our ecosystems.
3) Minimizing the use of ammonia-rich fertilizers on lawns would not add excess nitrogen to the nitrogen cycle. As a result, it would help decrease the pollution of food webs in the oceans, decrease soil acidity on land, and decrease the amount of greenhouse gases in the atmosphere
Explanation:
The nitrogen and phosphorus cycles both are biochemical cycles. The nitrogen cycle involves the process of uptake of nitrogen from the atmosphere by the soil bacteria which is then become available to the plants for plant growth, from plants it is transferred to the other organisms in different forms.
The phosphorus is found in the rocks and these rocks wither and the inorganic phosphorus become available to the ecosystems.
Option 1 is correct, this is because the phosphorus is available on earth in the inorganic form inside the rocks, the withering and erosion processes make the phosphorus available to the plants. Another source of phosphorus to plants is phosphorus rich fertilizers. Thus plants will absorb phosphorus and grow. These plants will be consumed by other organisms thus the ecosystem will remain healthy.
Option 3 is correct, this is because nitrogen rich fertilizers can cause eutrophication in water bodies, or can contaminate the water. It will decrease the pH of the soil due to the formation of nitric acid. Also the nitrogen dioxide is the greenhouse gas.
Some of the health consequences of our ability to move about and live almost anywhere in modern times are as follows:
- Potent to adapting to the new environment.
- The proximate effects of global change on those values.
- The future of the social and economic organization of that specific region.
- Alterations in the thoughts and emotions by analyzing different cultures of the various locations.
<h3>What do you mean by Health consequences?</h3>
Health consequences may be defined as any remarkable adverse experience that includes those that may be either life-threatening or involve permanent or long-term injuries, but excluding injuries that are nonlife-threatening and that are temporary and reasonably reversible.
It directly interacts with skin cancer and with mental health because when you move and live almost anywhere in modern times, you have exposed to high moderate levels of radiation from the sun. It causes tanning and other skin infection that potentially rises to skin cancer.
