How Saving Wildlife Benefits Humans

It’s no secret that we’ve lost an overwhelming number of species within that last four decades. These species have all but _____ due to overpopulation, deforestation, consumer culture, climate change, animal exploitation, and other harming sources — all brought about by mankind.

One of the first great rules of terrestrial (陆地的) biology is “no species is forever.” _____, this rapid loss of species today is estimated to be between1,000and 10,000 times higher   than the natural extinction rate. As increasingly accepted theories have argued, we are now in the midst of the sixth great _____.

The Earth consists of plants, animals, water,   land, the atmosphere, and humans.   Biodiversity (生物多样性) _____ the health of the planet and has a great impact on all our lives. Reduced biodiversity means a future where food supplies are vulnerable (易受攻击的) to pests and disease, and fresh water is   in short supply. If biodiversity _____ impacts   our lives in such big   ways, then our conservation (环保) efforts don’t just benefit the environment, they benefit us, too.

One convincing benefit that comes from wildlife conservation efforts is that it ensures food _____. Wildlife conservation promotes agricultural biodiversity, which plays an important role in building a secure and healthy food system. When agricultural biodiversity is _____ and land   is cleared for agriculture, extensive habitat loss takes place, as well as undocumented loss of species and massive soil erosion (侵蚀).

Another benefit that comes from wildlife conservation is that these _____ protect human health. Conservation International reportsthat “more than 50 percent of modern medicines and more than 90 percent of traditional medicines   come from wild plants   and animals.” _____,   a     world that promotes healthy ecosystems and biodiversity provides crucial buffers (缓冲) between disease and humans. A number of studies have _____ reduced diversity among mammal (哺乳动物 ) species and overall decreases in biodiversity to an increase in the transmission ( 传 播 ) of animal-born diseases to humans.

Perhaps the most convincing benefit that comes from wildlife conservation is that it provides us with _____ whether it be economically or socially. Increasing biodiversity and   healthy ecosystems improve agricultural productivity, thereby allowing farms to become more _____. Healthy ecosystems that are home to unique species _____ tourists from around the world, which helps the local economy and invites in a new fusion of investment.

Our unsustainable, unconscious, self-interested relationship with the environment has led us into an extremely destructible world. If we do not take action and _____ changing our ways, we     are at risk of losing more vital and _____ ecosystems and biodiversity,   or at least until the sixth   great extinction claims one final species: our own.

【推荐2】Keeping The Taps Running in Thirsty Cities

Water covers 71% of Earth’s surface yet only 2% of it is accessible as a source of fresh water. ______ on this limited resources is rising, a trend likely to continue.

It is important to recognize that it is not just city residents who ______ water. Agriculture, industry and tourism often require more water than the municipal water supply. Globally, 70% of fresh water is ______ for agriculture, but locally in heavily irrigated(灌溉)areas this can increate to 90%. A healthy environment also requires fresh water, and the quality of available water is as important as its ______.

Water stress is not always caused by physical shortages in dry areas. ______ for water resources between different users within river catchments or basins can also be a cause.

Every thirsty city operates within its own context, _____ to the challenge of providing adequate water supplies. Cape Town, ______, has faced three years of drought during which winter rains failed to materialize. At the end of the 2017 rainy season the city faced the ______ of its dams running dry during 2018. The dams were only 37% full—in the same week four years before they were full to the top. In January 2018, it was ______ that Cape Town would reach Day Zero, when it would be forced to turn off the taps, in April. This was despite the city reducing its water use by more than half, from 1.2 billion litres a day in 2015 to fewer than 600 million litres, and working ______ with industry and agriculture to reduce demand.

On February 1, the authorities put in place a strict limit of 50 litres of water per person per day. ______, in Britain this is considered enough for a five-minute shower of half a washing machine cycle on full load.

In addition, a ban was placed on using ______ water for gardens, water management devices were installed at household with a high water use and the water pressure was reduced to cut demand and leaks. At the same, the city launched a media ______ to change habits and introduced higher duties. This is not without its costs; agriculture and tourism, both significant areas of employment, have ______. It is a classic example of the problem of water economics-the cost of water is low but the cost of a lack of water is very high.

Crises such as the Cape Town drought are in danger of becoming the new norm. The ______ of Day Zero must serve as a wake-up call for cities across the world to develop cost-effective water management strategies to cope with an uncertain future.

【推荐3】Climate Change: Yes, Your Individual Action Does Make a Difference

What can we do in the face of the climate emergency? Many say we should drive less, fly less, eat less meat. But others argue that personal actions like these are a pointless drop in the ocean when _____ the huge systemic changes that are required to prevent _____ global warming.

It’s a debate that has been raging for decades. _____ , in terms of global greenhouse gas emissions, a single person’s contribution is basically irrelevant (much like a single vote in an election). But my research, first in my masters and now as part of my PhD, has found that doing something bold like giving up flying can have a wider _____ effect by influencing others and shifting what’s viewed as “normal”.

In a survey I _____ , half of the respondents who knew someone who had given up flying because of climate change said they flew less because of this example. That alone seemed pretty impressive to me. Furthermore, around three quarters said it had changed their _____ towards flying and climate change in some way. These effects were _____ if a high-profile person had given up flying, such as an academic or someone in the public eye. _____ , around two thirds said they flew less because of this person, and only 7% said it had not affected their attitudes.

I wondered if these impressionable people were already behaving like squeaky-clean environmentalists, but the _____ suggested not. The survey respondents fly considerably more than average, meaning they have plenty of potential to fly less because of someone else’s example.

To explore people’s ______ , I interviewed some of those who had been influenced by a “non-flyer”. They explained that the bold and unusual position to give up flying had conveyed the seriousness of climate change and flying’s contribution to it; ______ the link between values and actions; and even reduced feelings of isolation that flying less was a ______ and sensible response to climate change. They said that “commitment” and “expertise” were the most influential qualities of the person who had stopped flying.

That people are influenced by others is ______ a shocking result. Psychology researchers have spent decades amassing evidence about the powerful effects of social influence, while cultural evolution theory suggests we may have evolved to follow the example of those in prestigious positions because it helped us ______ . Pick up any book on leadership in an airport shopping mall and it will likely ______ the importance of leading by example.
