Pesticides are used in public health and agricultural practices. They have chemicals compositions used to kill disease vectors in public health, and pests in agriculture. On the other hand, they are also harmful in agriculture and to public health. Pesticide effective use should not be compromised which necessitates proper understanding of both negative and positive aspects. This discussion is interconnected with the issue of pesticides (Cole 6).
Pesticides should be managed to promote their effectiveness and minimize environmental risks associated with them. When using pesticides, guidelines on data sheets, which contain toxicological information, are important. The environmental conditions are constantly changing making it hard to ban the use of pesticides. They help in agricultural production increase, which is a challenge due to the increasing population and limited land resource (Cooper and Dobson 4).
This calls for evaluation of every pesticide in determining its effects. Many studies developed, conclude that the negative impacts associated with pesticides outweigh the positive ones. The negative impacts are associated with incorrect pesticide applications before and after their use. In this view, if the application of pesticide were done correctly, then their benefits would outweigh risks.
To sum it up, the agriculture sector should work together with the health sector. This will promote correct use of pesticides while reducing negative health implications associated with pesticides. If there is a total ban of pesticides usage, environmental risks associated with pesticides will be well controlled.
On the other hand, out of reduced agricultural production, there will be little to feed the highly increasing population. In addition, complete pesticide ban is likely to promote immense environmental damage because of poor farming methods in relation to land needs.
Water scarcity
Water scarcity is a concept, which is related to high demand of water and low availability of this resource. As the population increases, the demand for water also increases. Water is a renewable resource, but the rate at which this resource is renewed, seems to be low as compared to the demand.
Water scarcity has some relationship with access to safe drinking water and food supply. Water management is a tool for every person to reduce the water shortage. Legislatures on water management are necessary in curbing the problem (United Nations 6).
Human beings have the right to access and use safe drinking water. However, it has not been possible to exercise the right. Proper water management of water is likely to promote access to safe drinking water for all. Water is vital in life promotion. Therefore, its scarcity threatens food supply due to reduced food production.
Crop production requires a large amount of water thus; the shortage affects the food supply. Global water management is necessary to reduce the shortage globally. Climate change through global warming is the leading cause for water shortage thus there is the need to reduce global warming in all nations.
Governing global legislature in relation to water management is also notable. Increase in water price is likely to reduce the consumption as this reduces water wastage. I would not consider the use of treated grey water for direct consumption but in other areas such as agriculture. My efforts are beneficial in reducing water usage for instance; reducing the time I spend on the shower.
Some environmental implications are related to water shortage, among them are environmental health implications due to poor sanitation because of water shortage that in its turn promotes the spread of waterborne diseases like cholera and dysentery. Water shortages also depresses agricultural production; thus, food security is threatened ( CIEL and WWF 7).
