Since the 1960s, the human population has roughly doubled and it is likely to rise by another third by 2030. This will of course lead to increased demands for food, water, energy, and space to live, necessarily putting us in competition with other species - and, if the past is anything to go by - with obvious results. Humans already use 40% of the world's primary production (energy) and this is bound to increase, with serious consequences for nature. We are fast losing overall biodiversity, including micro-organisms in the soil and sea, not to mention both tropical and temperate forests, which are to maintaining productive soils, clean water, climate regulation, and resistance to disease. It seems we take these things for granted and governments do not appear to factor them in when making decisions that affect the environment.
One prediction that has been made is that, in the UK at least, warming and the loss of habitats could lead to more continental species coming to live here, and that in towns and cities, we will have more species that have adapted to urban life and living alongside humans.

Correct answer: global
Explanation: The term 'global' fits grammatically as it describes trends that are worldwide in scope, aligning with the context of discussing significant trends that affect the future. It also matches the plural noun 'trends' in number, indicating that these trends are not limited to a local or typical scale.
Meaning: 'Global' means relating to the whole world, indicating that the trends being discussed have a worldwide impact.
Wrong options:
- local: The word 'local' refers to a specific area or community, which contradicts the context of discussing large, impactful trends that are not confined to a single location.
- new: While 'new' suggests something recent, it does not convey the extensive reach of the trends being discussed, which are characterized by their global nature.
- typical: 'Typical' implies something that is usual or standard, which does not capture the significance of the trends that are described as large and impactful.
Correct answer: Indicators
Explanation: The word 'Indicators' is appropriate as it refers to signs or signals that provide information about future conditions, fitting well within the context of predicting environmental changes. It is also plural, matching the context of multiple signs being discussed.
Meaning: 'Indicators' are signs or pieces of information that suggest what may happen in the future, particularly regarding environmental conditions.
Wrong options:
- Pointers: 'Pointers' can refer to hints or suggestions, but it is less formal and specific than 'indicators' in the context of forecasting future trends.
- Signposts: While 'Signposts' can indicate direction, it is more metaphorical and less commonly used in the context of environmental predictions compared to 'indicators.'
- Premonition: 'Premonition' implies a strong feeling about a future event, which is more subjective and less factual than the objective nature of 'indicators'.
Correct answer: growth
Explanation: The term 'growth' fits grammatically as it is a noun that describes an increase in size or number, which aligns with the context of population changes. It is also a common term used in demographic discussions, making it contextually appropriate.
Meaning: 'Growth' refers to an increase in the number of individuals in a population, indicating a rise in population size over time.
Wrong options:
- development: 'Development' refers to the process of growth or progress, but it does not specifically denote an increase in numbers, making it less precise in this context.
- rises: 'Rises' is a verb form that does not fit grammatically as a noun in this context, where a noun is required to describe the population change.
- explosion: 'Explosion' suggests a sudden and dramatic increase, which may carry a negative connotation and does not fit the neutral tone of the passage.
Correct answer: crucial
Explanation: The word 'crucial' is appropriate as it indicates something of great importance or essential to a situation, fitting well within the context of discussing the importance of forests for environmental health. It matches the tone of urgency in the passage.
Meaning: 'Crucial' means extremely important or necessary, highlighting the vital role of forests in maintaining ecological balance.
Wrong options:
- favorable: 'Favorable' suggests something that is advantageous, but it does not convey the essential nature of forests as 'crucial' does in this context.
- decisive: 'Decisive' implies a determining factor, which does not capture the ongoing importance of forests in environmental sustainability as effectively as 'crucial.'
- effective: 'Effective' means producing a desired result, but it lacks the emphasis on necessity that 'crucial' provides in this context.
Correct answer: rare
Explanation: The term 'rare' fits grammatically as it describes habitats that are uncommon, aligning with the context of discussing environmental changes and their impacts. It is also consistent with the plural noun 'habitats,' indicating that these habitats are not frequently found.
Meaning: 'Rare' means not occurring very often, indicating that the habitats in question are uncommon and thus significant in the context of environmental predictions.
Wrong options:
- unusual: 'Unusual' suggests something that is not typical, but it does not carry the same implication of infrequency as 'rare' does, making it less precise in this context.
- common: 'Common' implies something that is frequently found, which contradicts the context of discussing habitats that are diminishing and becoming less prevalent.
- human: 'Human' refers to people and does not fit the context of describing types of habitats, making it irrelevant in this scenario.
