Precipitation deficiency can cause loss of soil moisture. All droughts can be affected by precipitation deficiency, but the drought most often caused by precipitation deficiency is Hydrological. The two droughts above are very different and have that one similarity. There are actually are four types of droughts, Meteorological droughts and Socioeconomic droughts and the other two above. In conclusion, the two droughts are very different.
Thus, when forests are removed, it is less likely to rain. There will also be lesser trees to facilitate more water to infiltrate the ground and funnel water into underground aquifers where it is stored to supply during droughts. Hence, deforestation has resulted in flash flood during heavy rainfall, and without the roots holding the soil, it will eventually lead to soil erosion. Furthermore, the soil will be washed away into rivers when there is heavy rainfall, causing river carrying capacity to be reduced and thus, increasing the risk of floods. Both droughts and floods carry severe consequences as eroding topsoil, flooding rice fields and filling in irrigation canals will constrain food production.
The results of this experiment highlight the dangerous effects of water pollution from indiscriminate use of detergents on plants. Thus, it is important that we use environment friendly detergents and governments start treating sewage/ polluted water before letting it into rivers and streams. The growth results have been depicted in the following graph: The average height of plants in each pot has been taken in centimetres and the growth was measured for 21 days. (VIII) CONCLUSION: The plants in Pots 4 and 5 did not sprout. The growth in Pot 0 was the highest as there was no detergent mixed in the water supplied to it.
The leaf length decreased at an average rate of 1mm per day over the 13 days. Plant D’s leaf width decreased for the remaining 10 days of the experiment. The leaf width decreased at an average rate of 0,2mm per day over the 10 days. There was a burst of 2mm growth between Day 16 and Day 19 which could have been due to increased sunshine resulting in more favourable conditions or the growth could have been random. From the graph on page 10 indicating Plant D’s growth, it is evident that Plant D began to grow at a standard rate due to the positive gradient evident.
• Increased habitat loss. Because of increasing human population, we have to extend the use of land into certain areas. Humans have moved to places that was once not susceptible for living. Many rainforest is being converted into an urbanized land. • Environmental degradation and depletion of natural resources.
Freshwater supply and the amount depend on the ecosystem. It plays a serious role in the circulation, cleaning and filling water supplies. Climate change has triggered the melting of polar ice caps and causing water levels to rise. Due to climate change, a layer of snow melt and soil will absorb more solar heat. The loss of wetlands has made the lack of the ability of a region to facilitate the ecosystem, as well as migratory species because they needed a more viable than ever and the weakening of regional capacity to absorb storm surges.
due to the over population, the number of various chemical elements in increasing in the atmosphere which ultimately causes irregular rainfall and global warming. It is very true that climate changes goes slowly, however continuous slow process is very dangerous. because regular changes in the environment physical structures of the human beings and other living species has been changed from generation to generation. Increasing human population needs more land for agricultural cultivation and living purpose which force them to cut more trees and forests so the deforestation has its own dangerous side effects. I believe everyone present can agree that all of these issues exist and that humans have caused them.
As humanity becomes more advanced, some people are forgetting to pay attention to the most important thing, Earth. Humans are unintentionally causing irreversible damage to the surface of the Earth. Deforestation is caused by the need for living space, wood, and other natural resources. While clearing out forests, many species are going extinct because of habitat loss and pollution. In other parts of the world, land degradation, which is caused by intense agricultural practices is preventing food security in many developing countries.
Therefore, to deal with this and ensure sustainability of the rainforest; it is vital to analyze the causes and the effects of the deforestation before it reaches the crisis point. The first main cause of rainforest destruction is the rapid population growth. To support a huge number of populations, expand the agriculture activities are needed. For such type of expansion, more money is required for the process and the only way to ensure that the consumption is enough is to use an alternative method that uses less money. The slash-and-burn cultivation technique requires little capital cost since it is cheaper and quicker, thus
It is due mainly to climate variability, and unsustainable human activities. Desertification, in its classical definition, refers to the rapid depletion of plant life and the loss of topsoil usually caused by a combination of drought and the overexploitation of grasslands and vegetation by the people. In addition, the abuse of humans on land areas together with the harsh climate increases the chance of the land to corrode. It
