a. This daily traffic jam not only creates serious safety hazards for students walking to school but also generates dangerous levels of local air pollution.

b. This scheme requires parents to park a few streets away and walk the remaining distance with their children.

c. Every morning, the roads outside our school become heavily congested with parents dropping off children in cars.

d. As a result, the immediate area around the school entrances would become significantly safer and the morning air would be noticeably cleaner.

e. To address this issue, the administration should introduce a special 'park and stride' programme for families living further away.

a. This simple technical change would immediately cut the total amount of paper used in classrooms by exactly half.

b. Furthermore, teachers should be strongly encouraged to accept homework assignments through online learning platforms rather than collecting printed assignments from students.

c. Despite having digital devices, many schools still rely on printed worksheets, resulting in thousands of wasted pages weekly.

d. By combining these two practical methods, educational institutions can successfully minimise their environmental impact while saving a considerable amount of money.

e. The first necessary step to reduce this massive waste is to set all school network printers to double-sided printing as the default option.

a. A practical way to resolve this issue is for food vendors to switch entirely to natural materials like banana leaves or paper.

b. Street food stalls are incredibly popular in our city, but they unfortunately use excessive amounts of single-use plastic takeaway packaging.

c. Taken together, these collaborative actions would significantly reduce the huge volume of rubbish produced daily by the fast-growing takeaway food industry.

d. In addition to this change, customers should receive a small discount if they bring their own clean reusable containers.

e. Because most of these cheap plastic boxes and cups are never recycled, they eventually end up polluting our local streets and waterways.

a. This daily practice represents a terrible waste of valuable resources, especially when many poor families struggle to afford basic meals.

b. Another highly helpful idea is to utilise specific mobile apps that sell near-expiry food items at discounted prices to interested nearby residents.

c. To prevent this wasteful practice, shop owners should partner with local charities to donate their leftover items at closing time.

d. Every evening, local bakeries and neighbourhood grocery stores throw away a surprisingly large amount of unsold but perfectly safe and delicious food.

e. Both of these practical solutions guarantee that fresh food is consumed by people rather than needlessly ending up in overflowing bins.

a. Leaving these energy-intensive appliances switched on when no one is inside wastes a huge amount of expensive electricity over the entire academic year.

b. These smart devices would automatically turn off the overhead lights and cooling systems whenever a particular room is left empty for several minutes.

c. It is common to see school classrooms left empty during break times with lights and air conditioners still running.

d. Besides saving precious energy resources, this technological upgrade would noticeably lower the school's monthly electricity bills and free up funds.

e. To stop this continuous energy waste, the school board should install modern motion sensors in every room and corridor.
