Urban Trees Are Threatened by Climate Change

By 2050, about three-quarters of the species will be at risk as a result of climate change, a study has found. Cities around the world may need to start planting different types of trees and shrubs that can     1     warmer and drier conditions.

“By ‘at risk’, we mean these species might be     2     stressful climatic conditions,” says Manuel Esperon-Rodriguez at Western Sydney University in Australia. “Those trees are likely to die.”

City trees have many benefits, from making urban spaces look beautiful and providing a refuge for wildlife to keeping places up to 12°C cooler than they would otherwise be in summer. Losing tree     3     would lead to cities becoming even hotter as the planet heats up.

To     4     the threat, Esperon Rodriguez and his colleagues used database called the Global Urban Tree Inventory to work out the conditions required by 3100 tree and shrub species currently grown in 164 cities worldwide. The researchers then looked at how these conditions would be affected by climate change under medium-emissions scenario known as RCP 6.0.

By 2050, 76 per cent of these species will be at risk from rising     5     temperatures and 70 percent from decreasing rainfall, the team concludes.

The study doesn’t take account of       6     urban growth, which could warm cities even faster. Nor does it take account of greater weather     7     caused by climate change, or the effects of pests and diseases. Warmer conditions are allowing more pests, such as bark beetles, to survive winters as well as to reproduce faster in summer, greatly increasing their     8    .

“Our     9     have scientific basis,” says Esperon-Rodriguez. There are some things that can be done to help trees survive. The best strategy is to choose tough species when     10     trees or planting new ones, the team concludes.

6 . Directions: Read the following passage. Summarize in no more than 60 words the main idea of the passage and how it is illustrated. Use your own words as far as possible. 

Are we greening our cities, or just greenwashing them?

Architecture and urban design is chasing a green fever dream. Everywhere you look, there are plans for “sustainable” buildings, futuristic eco-cities and aquaponic farms on the roof, each promising to add a green touch to the modern city.

All of these are surely good ideas at some level. They are trying to repair some of the damage our lifestyle has done to the planet. But, despite the rhetoric of reuniting the city with nature, today’s green urban dream is too often about bringing a technologically controlled version of nature into the city and declaring the problem solved, rather than looking at the deeper causes of our environmental and urban problems.

One of the most striking examples is Apple’s “spaceship” campus now under construction in Silicon Valley. Though it seems to be sustainable and energy efficient—80 percent of its 175-acre site is preserved for landscaping, it is by any measure a huge, expensive and massively resource-intensive project. As a suburban white-collar workplace, it must include vast garages for 13,000 Apple employees. Thus, it will leave no smaller environmental footprint than a traditional office park.

Designing a perfect green building or eco-city isn’t enough to save the world. Although our buildings, like our cars, have been inefficient environmentally, architecture isn’t directly responsible for humanity’s disastrous environmental impacts. An economic system based on the destruction of nature is the real problem. No green building can help us repair the ecological damage we have caused, nor can any number of aquaponic farms bring us back to the real nature.

Instead of adding “nature” to the urban lifestyle, architects may work to design better relationships between our cities and nature, and to promote just relationships between the people in them.
