In this Grade 5 hard worksheet, learners analyze cause-and-effect chains in human impact problems and design real solutions. They evaluate scenarios about thermal pollution, urban tree planting, community funding choices, and plastic bag bans across cities. Five fill-in items cover extinction, nature reserves, sustainable agriculture, ecologists, and service projects, helping students design and explain strong conservation plans for their own communities and neighborhoods.

Human Impact on the Environment
Part A: Multiple Choice
Circle the best answer for each question.
1. A factory dumps warm water into a river daily. Which chain of effects is MOST likely?
A) River cools, oxygen rises, more fish thrive
B) Water warms, oxygen drops, fish struggle to survive
C) Plants grow faster only, no animal effect
D) Water freezes earlier each winter
2. Read: 'A neighborhood plants 200 trees along streets and parks.' Which long-term result is MOST likely?
A) Less shade and hotter sidewalks
B) Cleaner air, cooler streets, and more bird habitats
C) Fewer insects and birds in the area
D) Higher carbon dioxide near the trees
3. A community can only fund ONE plan. Which gives the BIGGEST environmental benefit?
A) Buy disposable cups for the town hall
B) Pave a new parking lot in the park
C) Add solar panels and recycling bins to the school
D) Replace bikes with extra cars for staff
4. After a city bans single-use plastic bags, which outcome is MOST expected over years?
A) More plastic in oceans
B) Less plastic litter and lower waste in waterways
C) More turtles eating plastic bags
D) Higher landfill volume from bags
Part B: Fill in the Blank
Write the correct answer on each line.
1. When a species disappears forever from Earth, it becomes extinct.
2. An area set aside to protect wildlife is called a nature reserve.
3. Farming methods that protect soil and water are called sustainable agriculture.
4. A scientist who studies how living things interact with the environment is an ecologist.
5. Working as a community to clean a park is called a service project.
