As the global population increases rapidly, societies around the world need to come up with more efficient solutions to controlling waste. Excess litter and refuse pose a serious threat to the environment. Illegal dumping and littering are two of the major contributors to pollution in our rivers, oceans, public spaces and countryside. Keeping our environment clean is a collective responsibility that we all share.
Every citizen has a role to play in protecting the environment from pollution. We need to eradicate litter and avoid irresponsible waste disposal practices immediately. There is no excuse for plastic waste in the environment – it should always be recycled and thrown away in a responsible manner. Make a point of finding out more about what can and can’t be recycled, and start separating at home. Plastic is a valuable resource that is too important to simply dump and never use again.
We need to reduce, reuse and recycle our waste wherever possible. This will keep litter out of the environment. The South African Department of Environment, Forestry and Fisheries is concerned about the amount of pollution in our rivers, dams and oceans. Every South African needs to take responsibility for their waste and disposal habits.
Answer:
"When your body has to regularly break down that much alcohol, your blood and the functional cells in your liver accumulate a lot of potentially damaging toxic byproducts."
Explanation:
Excessive alcohol consumption, as the man exposed in the question consumes, negatively affects the body's metabolism as ethanol is metabolized by the liver, where harmful substances such as acetaldehyde are released after alcohol is metabolized. It is also known that alcohol consumption generates oxidative damage, free radical accumulation and depletion of hepatic anti-oxidative capacity. In this context, we can conclude that excessive alcohol consumption accumulates toxic byproducts in the body.
Therefore, we can conclude that what the nurse would say to the man presented in the above question is: "When your body has to break down that much alcohol, your blood and the functional cells in your liver accumulate a lot of potentially damaging toxic byproducts".
