You have been briefed by the Bird Guardians
on the importance of your mission. If you do
the following things carefully you will be able to save the bird and insect species....

These were the instructions given to some young time travellers visiting Princess Vlei from the year 2219.  The visitors had come from a future where there were no birds or bugs. A world full of sounds - bleeps,  sirens,  robotic voices,  and machinery. But not a twitter, nor a chirp, nor a buzz could be heard, where all greenery had disappeared under concrete, and all rivers and vleis were swallowed by plastic  waste.  
     Forty time travellers, from Buck Road Primary, Harmony Primary, Floreat Primary and Levana Primary schools, were greeted by a Spirit Guide (Denisha Anand), who told them how the vlei had once looked in the time of the first humans who lived there, and how those humans lived harmoniously with the plants and animals. 
     Then the time travellers went out wearing with face masks to ensure that they did not catch virues from the past or pass on any viruses from the future. They carefully observed the birds and insects to see how they lived, what they need, and what might threaten them.  They were guided by the Time Lords, (who were sometimes their teachers).

When the time machine was ready to leave, the Chief Time Lord, Brendon Bussy, blew a horn to warn the children that the portal was closing, and they had to run to get back or risk being stuck in 2019.
 
Back in the time machine, the time travelers reported on their findings and shared their pictures and maps. They all agreed that birds and insects are awesome, but there are many things threatening them, in particular pollution. Here are some of their observations:
 
“Birds have feathers to keep them warm, they travel to different places, this is what we call migration. They use their beaks to get the nectar out, because unlike humans they can’t use their hands.”
 
“We want to make people aware that they shouldn’t pollute these areas because it is hurting the birds and insects.”
 
“We found that birds are in danger because humans don’t really care, they just care about technology and that and don’t really take care of nature … Nature don’t need us, we need nature. And there is lots of pollution and the wetlands are their habitat and then some people … want to clear the wetlands for farming or to build houses.”
