By observing World Bee Day each year, we can raise awareness on the essential role bees and other pollinators play in keeping people and the planet healthy, and on the many challenges they face today.
Traveling is a fantastic way to relax and forget all about our daily worries, reconnect with nature, stretch our boundaries and discover incredible cultures. But, since there are so many things threatening our environment, with traveling comes the responsibility to protect nature.
If you love both traveling and nature, continue reading this article, and find out how to become a more sustainable traveler.
People are predominantly visual beings. We rely heavily on what we see to form our opinions and grasp the world that surrounds us. It is an important evolutionary tool, but it has been a double-edged sword. Hence we reach a particularly incendiary topic these days: climate change.
Bees and other pollinators, such as butterflies, bats and hummingbirds, are increasingly under threat from human activities.
Pollinators allow many plants, including many food crops, to reproduce. Not only do pollinators contribute directly to food security, but they are key to conserving biodiversity – a cornerstone of the Sustainable Development Goals. They also serve as sentinels for emergent environmental risks, signaling the health of local ecosystems.
Invasive insects, pesticides, land-use change and monocropping practices may reduce available nutrients and pose threats to bee colonies.
To raise awareness of the importance of pollinators, the threats they face and their contribution to sustainable development, the UN designated 20 May as World Bee Day.
Saving Our Beaches: Engineering Solutions for Tourists’ Impact
Everyone loves a beach vacation. In colder climates especially, more and more people are taking advantage of cheap airfares for a long weekend of sunbathing and swimming in the dead of winter. In fact, 12 of the top 15 destinations were in coastal countries.
In 1995, there were around 528 million international tourist arrivals. That number jumped to 1.138 billion in 2014, and emerging economies are experiencing faster tourism growth than advanced economies, making the increase in tourism an important part of many countries’ growth.
Local economies encourage increased tourism, as it helps to grow local wealth and jobs that pay well. Unfortunately, this relaxing trend is having some serious consequences on the environment that may outweigh the economic benefits.
Some of the downsides of increased tourism include resort development, boating, snorkeling, diving, and fishing, cruise ship presence, litter, coral reef damage, and even the creation of artificial beaches. These activities introduce toxins and other harmful substances, cause physical damage and sedimentation, and exploit local fish populations.
So what can be done to preserve the benefits of tourism for developing economies while balancing the need for environmental responsibility? Engineers have a few ideas. Eco-friendly roofing systems, designs that catch rainwater for later use, innovative wastewater management, and considering the landscape when constructing resorts and hotels can all help to reduce the impact tourists have on the local environment.
These innovative solutions are key for helping to ensure that tourists, locals, the local environment, and wildlife can all exist harmoniously now and in the future.
